Title: Method and compositions for enhancing the utilization of iron by mammals
IPC: A61K31/295
Filed: 1963-04-08
Abstract: Compounds of the formula <FORM:0998290/C2/1> where A is a phenylene or naphthylene radical which may be unsubstituted or substituted by one or two halogen atoms or one or two alkyl groups and where the OH group attached to each A is ortho to the methylene bridge connecting A to N, or alkali metal (including ammonium) salts of such compounds, are prepared by reacting formaldehyde with ethylenediaminediacetic acid or the corresponding alkali metal salt to form the dimethylol derivative which is then condensed with the appropriate phenol to form the desired product.  Iron chelates of these compounds, which are useful medicinally (see Division A5), can be obtained by adding to an aqueous methanol solution of such a compound an aqueous solution of an iron salt, e.g. ferric chloride.  An example illustrates the preparation of the disodium salt of N,N1-bis-(2 - hydroxy - 5 - methylbenzyl) - ethylene-diaminediacetic acid and the formation of an iron chelate therefrom.  The Specification also describes the preparation of the disodium salt of N,N1-ethylene-bis-(a  - imino - 2 - hydroxy - 5 - methylphenylacetic acid) from the corresponding free acid, the latter being obtained according to the method described in Specification 782,928, and the formation of an iron chelate from the disodium salt in a manner similar to that described above.ALSO:Compositions for use in administering iron to mammals comprise a solution, in a pharmacologically acceptable vehicle, of either an iron chelate derived from a compound of the formula <FORM:0998290/A5-A6/1> wherein A is a phenylene or naphthylene radical either unsubstituted or substituted by one or two halogen atoms or one or two alkyl groups and in which the OH group attached to each A is ortho to the methylene bridge connecting A to N, or a water-soluble, e.g. sodium, potassium or ammonium, salt thereof, or an iron chelate derived from a compound of the formula <FORM:0998290/A5-A6/2> wherein B is a phenylene or naphthylene radical having the OH group ortho to the carboxymethylene group connecting B to N and optionally containing one or two alkyl groups or one or two halogen atoms, or a water-soluble, e.g. sodium, potassium or ammonium, salt thereof.  The vehicle may be mammalian milk or orange juice when the compositions are administered orally, or water, peanut oil, sesame oil or polyvinyl pyrrolidone for parenteral administration.  The compositions may also be converted to dried, storable forms, e.g. by spray drying, which are reconstitutable by the addition of water.

Filed: 1951-06-11
Abstract: 711,225. Feeding sheets &c. MILLERLAUFFER PRINTING EQUIPMENT CORPORATION. June 11, 1951, No. 13843/43. Addition to 711,223. Class 100 (1) Pile supports; sheet carriers and separators.- In an apparatus according to the parent Specification, the feed belt is advanced by a variable speed electric drive, one speed being fast enough to oversupply envelopes to the chain-carried fingers, the speed being controlled by an electric switch actuated by a lever in sensing relation with the stack of envelopes, such that a deficiency in the supply of envelopes causes actuation of the switch in a direction to cause an increase in belt speed. Envelopes on edge are fed on belts 32, 33 and 40, 41 towards a pair of parallel adjustably spaced apart chains 11, 12 carrying fingers 16 which engage the flap folds of the envelopes at a position C, such that envelopes are conveyed by the chains to a printing press (not shown). The belts 32, 33 are driven by pulleys 34, 35 mounted on a shaft 36 driven through a pulley 37 and belts 38 by an electric motor 39. The belts 40, 41 are driven at a constant speed by pulleys 44, 45 on a shaft 47 driven by a worm-drive from an electric motor driving the chains. A pivoted lever 50 having a roller 51 is pressed against the top edges of the envelopes as shown, or alternatively against the bottom edges, such that owing to a break in the stack of envelopes, the lever pivots to cause the closing of an electric switch 55 in the circuit of the motor, such that only part of a resistance 58 is included in the motor circuit, thus increasing the speed of the belts 32, 33. Thus, more envelopes are fed to the belts 40, 41, thereby causing in due course, the lever 50 to open the switch 55 to reduce the motor speed and that of the belts 32, 33.

A method of stitching patch pockets on to a garment comprises the steps of folding three edges of the pocket around a former and then removing the former and sewing around these edges with the aid of a movable workplate having a slotted guide track which is moved by two pneumatic or hydraulic cylinders at right angles to each other and causing intermittent movement so that there is no movement while the needle is in the material. A patch pocket is located on the workplate and passed under the pressure plate 8 and pressed down by springs under the ends 17 of carrier arms 10. The former plate 11 is pushed by piston and cylinder unit 12 between the pocket and the garment and cross bar 16 pulls cross bar 23 towards the former plate where slots 21 and rollers 23 cause blades 9 to fold the pockets under edges of the former 11. Further movement of cross bar 23 causes folding blade 24 to complete the folding action. Magnets 26 on the transparent pressure plate 8 trap the pocket between blades 8 and 11. The former 11 and folding blades 9, 24 are then withdrawn to allow stitching and the workplate has a cam rack slot into which a follower on the throat plate of the machine projects to define the shape of the pocket. The workplate can be moved to follow the profile by means of two ram units located at right angles to each other and which move the workplate relative to the machine only when the needle is out of the work.
